Taking DY-150 tank-riding of DaYun Motorcycle Company as an example, from the tank production process, the author analyzes the production methods which are commonly used in welding and the defects of using these methods, and proposes a way or measure to avoid welding defects. Further more, the author suggests a reasonable design structure and the newest production structure of tank. According to the design in motorcycle tank structure, the author has chosen a welding machine and welding robot, which successfully improve production process and achieve the goal of lower production costs. Finally, the author chooses a typical tank welding seam and reasonable welding process parameters, and then establishes a welding process card and gives testing methods of tank welding. Key words: the tank of motorcycle; analysis of welding; design about welding technique; testing methods of the fuel tank welding 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc200888685 摘要 PAGEREF _Toc200888685 \h I HYPERLINK \l _Toc200888686 Abstract PAGEREF _Toc200888686 \h II HYPERLINK \l _Toc200888687 1 绪论 PAGEREF _Toc200888687 \h 1 HYPERLINK \l _Toc200888688 1.1 问题的提出 PAGEREF _Toc200888688 \h 1 HYPERLINK \l _Toc200888689 1.2 国内外油箱焊接技术应用现状 PAGEREF _Toc200888689 \h 2 HYPERLINK \l _Toc200888690 1.2.1 国外油箱焊接技术应用现状 PAGEREF _Toc200888690 \h 2 HYPERLINK \l _Toc200888691 1.2.2 国内油箱焊接技术应用现状 PAGEREF _Toc200888691 \h 3 HYPERLINK \l _Toc200888692 1.3 本课题研究的主要内容及应用意义 PAGERE
